The shutdowns, first reported by Re/code, affect 64 employees at DailyCandy and three at Television Without Pity.

In a tweet, Television Without Pity said, "TWOP will cease operations on April 4, but our forums will remain open till May 31. To our fans: Thank you for your support over the years."

NBCU reps did not respond to requests for comment.

NBCU's Bravo acquired Television Without Pity in 2007. The site was launched in 2002 by co-founders Tara Ariano and Sarah D. Bunting, who had started out in 1998 with a blog analyzing "Dawson's Creek." (They left the website in 2008.) TWOP provided recaps and reviews with an edge, sporting the tagline "spare the snark, spoil the networks."

Comcast bought DailyCandy in 2008 for $125 million from investment firm Pilot Group. The idea at the time was that the fashion and lifestyle publication for women would mesh with Comcast's cable networks like E!. Since then, Comcast acquired NBCU -- with female-focused networks like Bravo and Oxygen -- but the hoped-for synergies with DailyCandy never materialized.

The closures of DailyCandy and TWOP come after NBCU last November announced it would shut down iVillage, the women-oriented website it acquired for $600 million in 2006, and combine its operations with Today.com.
